Research shows climate change carries greater risks for unborn babies than previously thought. Some of the alarming effects of global warming may include worsening health and wellbeing in later life.
There is increasing concern that the Atlantic Meridional Overturning Circulation (AMOC) may collapse this century with a disrupting societal impact on large parts of the world. Preliminary estimates of the probability of such an AMOC collapse have so far been based on conceptual models and statistical analyses of proxy data. Here, we provide observationally based estimates of such probabilities from reanalysis data. We first identify optimal observation regions of an AMOC collapse from a recent global climate model simulation. Salinity data near the southern boundary of the Atlantic turn out to be optimal to provide estimates of the time of the AMOC collapse in this model. Based on the reanalysis products, we next determine probability density functions of the AMOC collapse time. The collapse time is estimated between 2037-2064 (10-90% CI) with a mean of 2050 and the probability of an AMOC collapse before the year 2050 is estimated to be 59±17%.
A new paper published in the journal Science has warned that melting areas in the Arctic have become 'frontlines for resource extraction', describing it as a 'modern day gold rush'.
There has been a strong push to promote increased investments in new nuclear power as a strategy to decarbonize economies, especially in the European Union (EU) and the United States (US). The evidence base for these initiatives is poor. Investments in new nuclear power plants are bad for the climate due to high costs and long construction times. Given the urgency of climate change mitigation, which requires reducing emissions from the EU electricity grid to almost zero in the 2030s (Pietzcker et al.1), preference should be given to the cheapest technology that can be deployed fastest. On both costs and speed, renewable energy sources beat nuclear. Every euro invested in new nuclear plants thus delays decarbonization compared to investments in renewable power. In a decarbonizing world, delays increase CO2 emissions. Our thoughts focus on new nuclear power plants (not phasing out existing plants) in the US and Europe. In Europe, new nuclear power plants are planned or seriously discussed in France, Czechia, Hu
Report calls for better safeguards to prevent bioterrorists from weaponizing new technology
An investigation by conservationists has found evidence that deep-seabed mining of rare minerals could cause “extensive and irreversible” damage to the planet.The report, to be published on Monday by the international wildlife charity Fauna & Flora, adds to the growing controversy that surrounds proposals to sweep the ocean floor of rare minerals that include cobalt, manganese and nickel. Mining companies want to exploit these deposits – which are crucial to the alternative energy sector – because land supplies are running low, they say.
The excessive use of phosphorus is depleting reserves vital to global food production, while also adding to the climate crisis
United Nations Secretary-General António Guterres made clear Monday that securing a livable planet depends on stopping the "bottomless greed of the fossil fuel industry and its enablers."
Scientists are to pick a location that sums up the current Anthropocene epoch when Homo sapiens made its mark
The climate protest group Extinction Rebellion is shifting tactics from disruptions such as smashing windows and glueing themselves to public places in 2023, it has announced. A new year resolution to “prioritise attendance over arrest and relationships over roadblocks”, was spelled out in a 1 January statement titled “We quit”, which said “constantly evolving tactics is a necessary approach”.
The scientist who has borne the full brunt of attacks by climate change deniers, including death threats and accusations of misappropriating funds, is set to hit back.

The fast fall of PG&E after California’s wildfires is a jolt for companies considering the uncertain risks of a warming planet
Nonviolent protests are twice as likely to succeed as armed conflicts – and those engaging a threshold of 3.5% of the population have never failed to bring about change.
France’s troubled nuclear fleet a bigger problem for Europe than Russia gas Giles Parkinson 5 August 2022 44 frederic-paulussen-LWnD8U2OReU-unsplash - optimised nuclear 669 Shares Share 669 Tweet Before Peter Dutton’s Coalition charge off into yet another inquiry into the merits of nuclear power, they might want to take a closer look at what’s happening in Europe, where the failure of France’s huge nuclear power plant fleet is causing bigger problems for EU power supplies than Russia’s withheld gas supply. France has been delivering just a fraction of its energy production potential in recent months, and overnight the situation got worse when French power producer EDF announced another three power plants would curtail output because of rising temperatures. Rivers have become too hot in the latest heatwave to be used to cool the reactors. The majority of France’s 56 nuclear reactors are currently throttled down or taken offline due to a combination of scheduled maintenance, erosion damage (worryingly, mostly a
Two of the UK’s leading hospitals have had to cancel operations, postpone appointments and divert seriously ill patients to other centres for the past three weeks after their computers crashed at the height of last month’s heatwave.
Blistering heatwaves are just the start. We must accept how bad things are before can we head off global catastrophe, according to a leading UK scientist.
This exposé of the coterie of rightwing scientists hell-bent on destroying the cause of environmentalism is outstanding
We must do what we can to contain Vladimir Putin’s aggression in Ukraine. But we also need to be clear-eyed about it, and face the costs. Economics can’t be separated from politics, and neither can be separated from history. Here are eight sobering realities:
The most widely publicized threat to the Amazonian rainforest is deforestation. Less well understood is that public lands are being converted to private holdings in a land grab we’ve been studying for the past decade... Much of this land is cleared for cattle ranches and soybean farms, threatening biodiversity and the Earth’s climate.

Berkeley Earth, a California-based non-profit research organization, has been preparing independent analyses of global mean temperature changes since 2013. The following is our report on global mean temperature during 2021.
Violent rainstorms are already more frequent, and they will only get worse. Europe’s metropolises are working on ways to protect themselves.
...In the canopy, photosynthesis rates are up to a third higher on sunny summer days in the CO₂-rich patches. Over a growing season, the increase is about a fifth. These are big numbers: imagine if your annual income went up by a fifth. Photosynthesis is the forest’s carbon income.
There are several ways to remove carbon from the atmosphere. One is called bioenergy with carbon capture and storage, or Beccs. Here, vast acres of fast-growing plants are grown and then harvested and burned to generate electricity or make biofuel for vehicles.
A Devon project to provide housing and community facilities has had the ground sold from under it
As floods increase in frequency and intensity, chemicals buried in river sediments become “ticking time bombs” waiting to activate.
The IPCC is unequivocal: we must take urgent action to curb global heating and prevent catastrophe. Will our policymakers and the Cop26 conference be up to the task?
More than 1 billion marine animals along Canada’s Pacific coast are likely to have died from last week’s record heatwave, experts warn, highlighting the vulnerability of ecosystems unaccustomed to extreme temperatures.
On Sunday this week Zakaria ended his program with a concise description of an effective approach to address climate change – in just a few minutes he described how carbon fee-and-dividend could be made near-global. I won’t try to summarize his take – it’s impossible to match his clarity and brevity, which includes great illustrations.
